Alan Robinson and Walter Macfarlane have been the best of friends for 60 years. But the Oahu, Hawaii men, got a life-changing surprise just in time for the holidays when they discovered they’re actually biological brothers. Walter had been searching for his father and decided to get a DNA test. When the results came back, the anonymous username Robi747 came back as a match in many ears. Walter knew his friend Alan Robinson often went by the nickname Robi — and he used to fly 747 airplanes. After a few phone calls back and forth, the men learned they shared the same birth mother. The two best friends who are now brothers say it was the best Christmas present they could have imagined.
